Performance for Special Distinction
In order to receive additional recognition and/or support from EPA for its efforts within the Partnership, the
ENERGY STAR Partner may consider the following voluntary measures, and should keep EPA informed
on the progress of these efforts:

▪ Provide quarterly, written updates to EPA as to the efforts undertaken by Partner to increase
 availability of ENERGY STAR certified products, and to promote awareness of ENERGY STAR and
 its message.
▪ Consider energy efficiency improvements in company facilities and pursue benchmarking buildings
 through the ENERGY STAR Buildings program.
▪ Purchase ENERGY STAR certified products. Revise the company purchasing or procurement
 specifications to include ENERGY STAR. Provide procurement officials’ contact information to EPA
 for periodic updates and coordination. Circulate general ENERGY STAR certified product information
 to employees for use when purchasing products for their homes.

▪ Feature the ENERGY STAR mark(s) on Partner website and other promotional materials. If
 information concerning ENERGY STAR is provided on the Partner website as specified by the
 ENERGY STAR Web Linking Policy (available in the Partner Resources section of the ENERGY
 STAR website), EPA may provide links where appropriate to the Partner website.
▪ Ensure the power management feature is enabled on all ENERGY STAR certified displays and
 computers in use in company facilities, particularly upon installation and after service is performed.
▪ Provide general information about the ENERGY STAR program to employees whose jobs are
 relevant to the development, marketing, sales, and service of current ENERGY STAR certified
 products.
▪ Provide a simple plan to EPA outlining specific measures Partner plans to undertake beyond the
 program requirements listed above. By doing so, EPA may be able to coordinate, and communicate
 Partner’s activities, provide an EPA representative, or include news about the event in the ENERGY
 STAR newsletter, on the ENERGY STAR website, etc. The plan may be as simple as providing a list
 of planned activities or milestones of which Partner would like EPA to be aware. For example,
 activities may include: (1) increasing the availability of ENERGY STAR certified products by
 converting the entire product line within two years to meet ENERGY STAR guidelines; (2)
 demonstrating the economic and environmental benefits of energy efficiency through special in-store
 displays twice a year; (3) providing information to users (via the website and user’s manual) about
 energy-saving features and operating characteristics of ENERGY STAR certified products; and (4)
 building awareness of the ENERGY STAR Partnership and brand identity by collaborating with EPA
 on one print advertorial and one live press event.
▪ Join EPA's SmartWay Transport Partnership to improve the environmental performance of the
 company's shipping operations. The SmartWay Transport Partnership works with freight carriers,
 shippers, and other stakeholders in the goods movement industry to reduce fuel consumption,
 greenhouse gases, and air pollution. For more information on SmartWay, visit
 www.epa.gov/smartway.
▪ Join EPA’s Green Power Partnership. EPA's Green Power Partnership encourages organizations to
 buy green power as a way to reduce the environmental impacts associated with traditional fossil fuel-
 based electricity use. The partnership includes a diverse set of organizations including Fortune 500

 Additional Test Set-up Instructions
 When configuring a model for testing to the ANSI/AHAM AC-1-2020 and the IEC 62301 test
 methods to determine Cigarette Smoke, Dust, and Pollen CADR, Operating Power, and
 Measured Partial On Mode Power, the tester shall:
 Install the unit in accordance with manufacturer instructions. Use the manufacturer default
 (i.e., as-shipped) configuration for all secondary functions. However, if the model has network
 connection capabilities, follow the instructions below.
 Verify if the unit under test (UUT) has network connection capabilities:
 a. Network connections should be listed in the user manual or installation instructions.
 b. If no connections are specified, verify that the Room Air Cleaner does not have
 network capabilities by checking for the absence of network settings on the product
 (e.g., control panel or product display).
 If the UUT has Wi-Fi network connection capabilities, the capabilities shall be activated using
 any standard or optional hardware provided by the manufacturer 3, and the UUT shall be
 connected to an active communication link (including wireless Radio Frequency).
 a. The network shall support the highest and lowest data speeds of the UUT’s network
 function. Manufacturer shall specify connection information related to data speed.
 b. An active communication link is defined as the mechanism for bi-directional data
 transfer between the room air cleaner and one or more external applications,
 devices, or systems. An active connection is defined as the capability to pass traffic
 across the UUT endpoint and test network device endpoint.

3
 All non-standard networking equipment and gateways need to be provided by the manufacturer (e.g.,
Zigbee, Zwave, etc.) but Wi-Fi, Bluetooth, and Ethernet can be configured with non-manufacturer
provided equipment.
ENERGY STAR Program Requirements for Room Air Cleaners – Eligibility Criteria (Rev. April-2021) 5

c. If the UUT is equipped with multiple network capabilities (e.g., Bluetooth, Ethernet,
 etc.), ensure a Wi-Fi connection be made and all other capabilities shall remain in
 their default, as-shipped configuration (e.g., Bluetooth searching but not connecting).
 d. The tester shall configure the address layer of the protocol, taking note of the
 following:
 i. Internet Protocol (IP) IP v6 has Neighbor Discovery and will generally
 configure a limited, non-routable connection automatically.
 ii. IP can be configured manually or using Dynamic Host Configuration Protocol
 (DHCP) with an address in the 192.168.xxx.xxx Network Address Translation
 (NAT) address space if the UUT does not behave normally when autoIP is
 used. The network shall be configured to support the NAT address space
 and/or autoIP.
 e. The UUT shall maintain this live connection to the network for the duration of testing,
 with the exception of brief lapses (e.g., when transitioning between link speeds).
 f. Ensure there is a connection to the Wide Area Network (WAN) if required in the
 manufacturer’s instructions. Configure WAN connection according to manufacturer
 provided network connection requirements, if applicable.
 g. If the UUT needs to install any software updates, wait until these updates have
 occurred; otherwise, if it will operate without updates, skip these updates.
 In the case of a UUT that has no data/network capabilities, the UUT shall be tested as-
 shipped.

 Number of Units Required for Testing
 Representative Models shall be selected for testing per the following requirements:
 For certification of an individual product model, the Representative Model shall be equivalent
 to that which is intended to be marketed and labeled as ENERGY STAR. Because of the
 inherent statistical variance in counting low density particulate matter particles, manufacturers
 have the option of testing the unit three times, each time with a new filter. The measured
 performance (or mean of measured performance) of this unit and of all units sold must be
 equal to or better than the ENERGY STAR specification requirements:
 CADRTest (CADRTest_Mean) ≥ ENERGY STAR CADR Criteria
 Measured OzoneTest (Measured OzoneTest_Mean) ≤ ENERGY STAR Ozone Criteria
 Measured Partial On Mode PowerTest (Measured Partial On Mode Power Test_Mean) ≤
 ENERGY STAR Maximum Partial On Mode Power Criteria
 For certification of a Product Family, any model within that Product Family can be tested and
 serve as the Representative Model. Any subsequent testing failures (e.g., as part of
 verification testing) of any model in the family will have implications for all models in the
 family.
 A single unit of each Representative Model shall be selected for testing.

6 EFFECTIVE DATE
 Effective Date: The Version 2 ENERGY STAR Room Air Cleaner specification shall take effect on
 October 17, 2020. To qualify for ENERGY STAR, a product model shall meet the ENERGY
 STAR specification in effect on the model’s date of manufacture. The date of manufacture is
 specific to each unit and is the date on which a unit is considered to be completely assembled.

 Future Specification Revisions: EPA reserves the right to change the specification should
 technological and/or market changes affect its usefulness to consumers, industry, or the
 environment. In keeping with current policy, revisions to the specification are arrived at through
 industry discussions. In the event of a specification revision, please note that ENERGY STAR
 qualification is not automatically granted for the life of a product model.
